Really nice tool. As remarked in a previous comment, it would be better to be active only by pressing some key, or some other way to avoid interference when not needing the popup.

Although there is no Chinese that I wanted, but I have to say this is really helpful for learning Kanji. Really fast and convenient. Thank you very much!

I love this extension because it has saved me so much time looking up word definitions. Sometimes, you just want to check that you remember the reading or meaning of a word, or what an unknown kanji means, and rikaikun is great for that!
